Hi,
I found a reproducible bug in LuaJIT 2.0.0 as well as git HEAD (f772bed).
Here's the test case. Only tested on 64-bit LuaJIT running on OS X 10.8.2.
$ cat bug.lua
local ffi = require 'ffi'
ffi.cdef [[
struct timespec { int tv_sec; long tv_nsec; }
int nanosleep(const struct timespec *req, struct timespec *rem);
]]
local ret = ffi.C.nanosleep(ffi.new('struct timespec'), nil)
print(type(ret), ret)
$ luajit bug.lua
cdata cdata<struct timespec>: 0x0004bb90
I expected ffi.C.nanosleep to return int, not a struct timespec.
Anders
